Blackheart Crossbow String 33 1/4 In. Parker

The Blackheart Crossbow String 33 1/4 In. Parker is a precision replacement string engineered for Parker crossbow platforms. After decades in the field, any serious crossbow hunter knows that the bowstring is the heartbeat of your rig—wear it out, and your accuracy suffers, your shot integrity fails, and your season can slip away. This Blackheart string restores the responsiveness and consistency your Parker crossbow delivered from the factory, making it an essential maintenance item for competitive shooters and backcountry hunters alike.

Built with high-strand-count, durable synthetic fibers, the Blackheart Crossbow String resists creep and moisture absorption far better than older twisted-fiber designs. At 33 1/4 inches, this string matches Parker's factory specifications exactly, ensuring proper brace height, draw weight consistency, and cam timing—three variables that directly control shot grouping and kinetic energy delivery. The tightly wound construction minimizes fraying and reduces peep rotation, two common frustrations that degrade accuracy over a season of hard use.

If your Parker crossbow shoots sluggishly or groups have opened up after months of practice and hunting, the Blackheart Crossbow String 33 1/4 In. Parker is your path back to confidence. Installation requires basic loop-over-limb service—no specialized tools or tuning knowledge needed—and the payoff is immediate: tighter groups, cleaner shots, and the peace of mind that comes from equipment you trust. For anyone running a Parker platform, keeping a spare string on hand ensures you're never sidelined mid-season.
